If a user wants to implement a custom image into a report, which tool will they primarily use?

To implement a custom image into a report in Alteryx, the most appropriate tool to use is the Report Text Tool. This tool allows users to insert formatted text and images within a report layout. When incorporating a custom image, the user can simply adjust the image settings to include the desired visual, making it a versatile choice for enhancing the content of reports with graphical elements.

While other tools may have their specific functionalities, such as the Interactive Chart Tool for creating dynamic charts or the Render Tool for finalizing and outputting the report, they do not specifically focus on allowing direct integration of custom images in the way the Report Text Tool does. The Layout Tool is used for structuring the overall report layout but does not handle image incorporation directly. Hence, the Report Text Tool stands out as the primary choice for embedding custom images into a report.
